What is the difference between Jabra UC and MS headset models?

The UC (unified Communications) and MS (Microsoft) versions of Jabra headset are identical with the exception that the MS version will automatically set itself as the default device in MS TEAMS, Skype for Business and Lync applications.

Both the Jabra UC optimised and Jabra MS optimised versions will work for either application just fine.
